Response conflict theory,error rates and hybrid processing: A reply to McLeod

McLeod (1977) has proposed a parallel processing model of the psychological refractory period quite similar to an earlier model most recently adumbrated by Kantowitz (1974a). This article corrects some erroneous statements made by McLeod about the testability of the response conflict model and emphasizes the importance of error data in distinguishing among conceptually similar models of the PRP effect.     

Air Pollution and interpersonal Attraction1

It was predicted that negative affect associated with one component of air pollution (malodor) reduces attraction toward both similar and dissimilar strangers. In one experiment, 27 subjects rated attitudinally similar or dissimilar strangers while confined in a room whose atmosphere was ambient (no-odor control) or polluted by ammonium sulfide. Contrary to predictions, similar strangers elicited greatest liking in the polluted atmosphere. It was suggested that air pollution had increased attraction for another who might be experiencing the same disagreeable situation (i.e., “shared stress”). In a second experiment, this suggestion was examined by assuring subjects that they were alone and would not meet the similar or dissimilar person they rated. As predicted, exposure to either ammonium sulfide or butyric acid combined additively with attitudinal dissimilarity to depress liking, mood-affect, time spent in the setting, and ratings of the environment. These results were viewed as consistent with the reinforcement-affect model of attraction, but it was cautioned that the effects of air pollution may depend on social factors, such as shared stress, and dosage level of the pollutant.     

Extraversion and neuroticism in orienting reflex dishabituation

The present study examined the effects of extraversion (E) and neuroticism (N) as individual difference dimensions and of stimulus intensity on electrodermal orienting response habituation, test response, and dishabituation. Subjects were 162 college students selected from a screening sample of 860 as representing extreme groups of high, medium, and low E crossing with high, medium, and low N. Subjects in all nine resulting groups were habituated to criterion on auditory stimuli of 60, 80, and 100 db. A novel (test) stimulus and a dishabituating standard stimulus followed criteron habituation at each intensity. Results indicated that response amplitude for initial, test, and dishabituation responses was a direct function and that habituation rate (trials-to-criterion) was an inverse function of stimulus intensity. Extraverts habituated more rapidly than introverts at high intensity and gave smaller test and dishabituation responses. Some results differed when regression coefficients defined habituation rate and when first stimulus intensities alone were examined. Correlations among initial, test, and dishabituation responses and between each of these and the two measures of habituation rate are also reported. Results were interpreted as partially supportive of Eysenck's theory.     

Humeanism without Humean Supervenience: A Projectivist Account of Laws and Possibilities

Acceptance of Humean Supervenience and thereductive Humean analyses that entail it leadsto a litany of inadequately explained conflictswith our intuitions regarding laws andpossibilities. However, the non-reductiveHumeanism developed here, on which law claimsare understood as normative rather than factstating, can accommodate those intuitions. Rational constraints on such norms provide aset of consistency relations that ground asemantics formulated in terms offactual-normative worlds, solving theFrege-Geach problem of construing unassertedcontexts. This set of factual-normative worldsincludes exactly the intuitive sets ofnomologically possible worlds associated witheach possible set of laws. The extension ofthe semantics to counterfactual and subjunctiveconditionals is sketched. Potential objectionsinvolving subjectivity, mind-dependence, andnon-factuality are discussed.     

Radical Orthodoxy, Luther, and the Challenge of Western Secularization

This "Theology Update" analyzes the Radical Orthodoxy of John Milbank in light of Martin Luther's dialectic between Law and Gospel. Milbank and his colleagues attack contemporary secularized culture in a manner parallel to Luther's attack on the 16^th century Holy Roman Empire for being soulless, aggressive, litigious, materialistic, and finally nihilistic. By re–engaging the battle between Thomas Aquinas and Duns Scotus, the radical orthodox party seeks to become post–modern by making a half turn back to the pre–modern Thomas, for whom philosophy and theology were integrated, subject was united to object, and being could be understood as relational because the Trinity is relational. Luther is mistakenly dismissed when reducing him to Scotus' nominalism, however. Lutheranism complements radical orthodoxy's analysis of secularized culture; yet Lutheranism maintains an integrity to faith–as the presence of Christ–that this new school fails to grant.     

What Makes A Hero? The Impact of Integrity on Admiration and Interpersonal Judgment

Principled and expedient ideologies affect self-regulation and guide people along divergent ethical paths. A more principled ideology, indicative of higher claimed integrity, involves a greater personal commitment to ethical beliefs, standards, and self-schemas that facilitate positive social activities and help resist the temptation of illicit activities. Two studies showed that differences in reported integrity are related to people's preferences for and judgments of others. Those higher in integrity spontaneously described their heroes as more principled, honest, spiritual, and benevolently oriented toward others (Study 1). In addition, integrity was related to people's evaluations of characters who made ethical or unethical career decisions (Study 2). The judgments of those higher in integrity were greatly influenced by whether or not the decision was ethical but were largely unaffected by the consequences (career success or failure), whereas those lower in integrity were less influenced by whether the decision was ethical and more influenced by the career consequences.     

A Politically Liberal Conception of Civic Education

Liberal political theory is widely believed to be an inadequate source of civic commitment and thus of civic education primarily because of its commitment to what is perceived as a pervasive individualism. In this paper, I explore the possibility that John Rawls’s later political philosophy may provide a response to this belief. I first articulate a conception of liberal politics derived from Rawls’s idea of reflective equilibrium that generates an overlapping consensus about political principles among those who hold a wide variety of cultural and personal conceptions of the good. Next I develop the aims for civic education in a society that employs such a politics. Then I suggest the elements of the public school curriculum appropriate for such a civic education, including a robust multicultural education, intellectual reflection on the society’s history, and philosophical training that enables children to understand the events and policies of their nation as following from general political principles. I also consider the kinds of classroom practice that seem necessary to provide the motivation to engage in the process of the emergence of an overlapping consensus, including opportunities to develop and to reflect on the principles that may be included in the current consensus and to understand the way in which those principles relate to children’s developing conceptions of the good. Finally, I compare this conception of civic education to those of other liberal theorists.

Duration of auditory sensory memory in parents of children with SLI: a mismatch negativity study

In a previous behavioral study, we showed that parents of children with SLI had a subclinical deficit in phonological short-term memory. Here, we tested the hypothesis that they also have a deficit in nonverbal auditory sensory memory. We measured auditory sensory memory using a paradigm involving an electrophysiological component called the mismatch negativity (MMN). The MMN is a measure of the brain's ability to detect a difference between a frequent standard stimulus (1000 Hz tone) and a rare deviant one (1200 Hz tone). Memory effects were assessed by varying the inter-stimulus interval (ISI) between the standard and deviant. We predicted that parents of children with SLI would have a smaller MMN than parents of typically developing children at a long ISI (3000 ms), but not at a short one (800 ms). This was broadly confirmed. However, individual differences in MMN amplitude did not correlate with measures of phonological short-term memory. Attenuation of MMN amplitude at the longer ISI thus did not provide unambiguous support for the hypothesis of a reduced auditory sensory memory in parents of affected children. We conclude by reviewing possible explanations for the observed group effects.
